ISRC1 High Sample Rate
(Sets the higher of the ISRC1 sample
rates)
0000 = SAMPLE_RATE_1
0001 = SAMPLE_RATE_2
0010 = SAMPLE_RATE_3
1000 = ASYNC_SAMPLE_RATE_1
1001 = ASYNC_SAMPLE_RATE_2
All other codes are Reserved.
The selected sample rate is valid in the
range 8kHz to 192kHz.
The ISRC1_FSH and ISRC1_FSL fields
must both select sample rates referenced
to the same clock domain (SYSCLK or
ASYNCCLK).
ISRC1 Low Sample Rate
(Sets the lower of the ISRC1 sample
rates)
0000 = SAMPLE_RATE_1
0001 = SAMPLE_RATE_2
0010 = SAMPLE_RATE_3
1000 = ASYNC_SAMPLE_RATE_1
1001 = ASYNC_SAMPLE_RATE_2
All other codes are Reserved.
The selected sample rate is valid in the
range 8kHz to 192kHz.
The ISRC1_FSH and ISRC1_FSL fields
must both select sample rates referenced
to the same clock domain (SYSCLK or
ASYNCCLK).
ISRC1 INT1 Enable
(Interpolation Channel 1 path from
ISRC1_FSL rate to ISRC1_FSH rate)
0 = Disabled
1 = Enabled
ISRC1 INT2 Enable
(Interpolation Channel 2 path from
ISRC1_FSL rate to ISRC1_FSH rate)
0 = Disabled
1 = Enabled
ISRC1 DEC1 Enable
(Decimation Channel 1 path from
ISRC1_FSH rate to ISRC1_FSL rate)
0 = Disabled
1 = Enabled
ISRC1 DEC2 Enable
(Decimation Channel 2 path from
ISRC1_FSH rate to ISRC1_FSL rate)
0 = Disabled
1 = Enabled
ISRC1 Notch Filter Enable
0 = Disabled
1 = Enabled
It is recommended to enable the notch
filter for typical applications.
